See attachment
Step-by-step explanation:
So, first you want to find the area of the base of the tank. This is the length times the breadth (or height, same thing). 50 x 30 = 1500. This means that it will take 1500cm3 (1.5 litres) of water for each centimeter of height. 1.5 x 8 = 12, so it would rise 8 centimeters.
1. D; -5m+2m, because -5+2=-3
2. B; 4 terms, every part of an expression that's not the subtraction/addition sign counts as a term.
3. Not 100% sure about this one, but I'll go with B; 4x².
4. C; 5b, that term cannot be combined because the variable is different from the rest.
I hope this was helpful.
